Some students believe that if they drink a glass of milk before bed and would make them sleep longer what’s the independent vari
miss Akunina [59]

Answer:

Independent variable: Glass of milk

Dependent variable: Time of sleep

Control variable: same type of milk

Explanation:

Independent variable in an experiment refers to the variable that the experimenter manipulates or changes in order to get a response in another variable (dependent). In this case, the independent variable is the GLASS OF MILK taken before bed.

Dependent variable is that variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the dependent variable is the TIME OF SLEEP of the students.

A control variable or constant is the variable that is kept unchanged throughout the course of the experiment in order not to alter the outcome of the experiment. In this experiment, a control variable can be the SAME TYPE OF MILK taken by each student.

Tropical rainforests have high species richness of trees. Which of the following statements provides the MOST reasonable explana
Anastaziya [24]

Answer:

The MOST reasonable explanation is that<em> animals have diversified into the vast number of niches provided by tree diversity</em>.

Explanation:

The tropical rainforest as a biome is located in areas near the equator, where precipitations are abundant and the average temperature is elevated most of the year. As a result of the climatic conditions, this biome gives shelter to a huge number of living organisms. Also, the canopy structure provides many refuges for plants and animals and is an important source of food. It also favors interactions between species. For example, there are too many plant species that live in trees, such as bromeliads,  and at the same time they provide refuge to other small animals, like frogs.

There are also too many species in the rainforest that have not been discovered yet.
